How to build self-contained executable with gcc? [duplicate]

Question

I wrote a program, that uses a shared library installed on my system. This library is seldom installed on other systems. How do I compile my program so that the library doesn't need to be installed on other systems? I have the source code for the library available. What's the best way?

The other systems of course have the same architecture and OS.

Answer 1

Compile it as a static library and link that into the executable.
